Interesting post from MySQL's Zack Urlocker - namely:
"Last year we actually surpassed Oracle's web site in terms of traffic, as measured by Alexa. However, not to pick on Oracle, in the tech sector we also generate more traffic than Red Hat, Novell, SAP, Apache, JBoss, Eclipse, BEA, Borland, Gartner, eWeek and InfoWorld.
Beyond tech, we actually have more traffic than some popular "mainstream" brands including the Nike, United Airlines, AT&T, Honda, Toyota, Ford, Porsche, Shell, GE, Princeton University, Fender Guitars, Coca-Cola, McDonald's and Hooters.
Ok, I admit, this was not a scientific analysis (especially the comparison with Hooters), and we have less traffic than some household names like Apple, IBM, Microsoft and Intel. Nonetheless, MySQL's web traffic is larger than many of the top best-selling brands as reported by InterBrand. For an open source database company, that's pretty good!"
